|description = This data represents a time-varying colonial network in which countries are linked via colonial dependencies/histories. We provide it in an edgelist format in which the colonized country ‘nominates’ its colonizer. Therefore, a colonial dependency is denoted by the outdegree and consistent with the other edgelist formats we provide. In short, the network fulfills the following criteria:
• Time-Variant: i.e. countries at yearly intervals from 1789 to 2010
• Weighted: i.e. connections of countries have differing weights based on colonial status in that year
o existing colonial relationship has the value of 1
o no colonial relationship has the value of 0
o time before colonial relationship started has the value of 0
o past colonial relationship have differing values < 1
• Inclusion of not only European colonial powers, but every relationship in which power was asserted over a space which was and is not still the space of said nation state exerting the power through "colonialism"; e.g. USSR
• Directed: i.e. (analogous to survey data) countries that were colonized "nominate" their colonizers
|codingrules = The raw data is based on the COLDAT Dataset by Bastian Becker in combination with CEPII and own data collection. Relationships that we added were for example that Georgia ‘nominates’ Russia as colonizer from 1801-1990 and Iran (Persian Empire) as well as Turkey (Ottoman Empire) from 1555-1801. In line with CEPII we did not add military occupations of e.g. Poland – Germany during World War II. CEPII follows a somewhat non-transparent definition of colonial links, however, boiling it down would mean: a colonial relationship should involve long-term, civilian administration that includes significant settlement. Short-term military occupation does not fit within these criteria.

For calculating the decay the following logarithmic parameter was used:
1 / (1 + log(No. years since colony ends +1))
It has a quite rapid fall in values i.e. 0.59 one year after colony ends and 0.29 ten years after. However, the values tend to get small very slowly like for example 0.17 at 100 years after colonization.
